  • Patent number: 9400360
    Abstract: A modified TO-can assembly is provided that has greater versatility with respect to spatial constraints than known TO-can assemblies and that is suitable for use in a wider range of applications than known TO-can assemblies. The modified TO-can assembly has a receptacle that has been modified to receive an optical fiber through its side instead of through its end. Within the TO-can assembly, the optical path is folded in order to couple the light between the optoelectronic component of the TOSA or ROSA and the end of the optical fiber. The combination of these features provides the modified TO-can assembly with a compact profile that makes it more versatile with respect to spatial constraints and therefore suitable for use in a wider range of applications.

  • Patent number: 9274290
    Abstract: Techniques for coupling light from a waveguide array to a single mode fiber array are described. In an embodiment, lateral misalignment of an array of focusing lenses and an array of optical fiber ferrules held into alignment by a lens holder sub-assembly is compensated by tilting the lens holder sub-assembly with respect to the propagation axis of the light being coupled by the lens holder-subassembly. Since the amount of tilt can be adjusted according to the degree of lateral misalignment, lens holder sub-assemblies manufactured with varying degrees of misalignment may be utilized to couple light into single mode fiber-optic cable. In addition, the same technique can also be used to compensate for other defects as well, such as angular errors in manufacturing or placement of a turning mirror or prism used to direct light into the lens holder sub-assembly.
